No wardrobe malfunction for this star. Plus, she talks about gay marriage and Nashville.

Carrie Underwood always looks amazing. And now, in the February issue of Allure magazine (out Jan. 22), she's sharing a big secret about how she ensures she never has a wardrobe malfunction.

"Underneath every skirt, every dress, I'm wearing shorts," she explains. "So that everyone in the world knows, if I ever fell down, nobody would get a peek at anything."

Some other highlights:

On Hayden Panettiere's role in the new TV series Nashville (Panettiere has said she modeled her character after Underwood): "I'm not like that at all. It's juicy, but I hope not everybody thinks that everything goes down like that in Nashville, and we're evil. To be honest, I've been fortunate enough to work with other types of music — and we're the least drama-rific people."

On gay marriage: "I'm in favor of acceptance. And I am a Christian person, and I do love the Lord, and I feel no matter who you are, what you believe, how you live your life, it's not my place to judge. I don't have that power. I don't want that power. It's my place to love and to show God's love to other people, even if they don't live a life like I live. So that's where I'm coming from."

On family and independence: "My mom had a job, and she also took care of us, and she also took care of Dad — I always saw her pulling triple duty, doing more than I ever felt like she needed to. I made a promise to myself that it would be more of a team effort in my family someday. And because of that, I became more independent. But it was tough figuring out what kind of guy would work with what I did. Because you have your problems with both."
